Investigation of Pheromone-Based Factors That May Reduce Capture of Boll Weevils in Traps

There are instances where substantial numbers of weevils are discovered in fields, but respective traps fail to detect weevils during the preceding week(s).  We characterized the initial quality (pheromone content and blend) and pheromone release rates of lure dispensers.  We also investigated whether weevils in these areas may produce a pheromone blend that is different from that of the standard pheromone lure.
